Title: Active noise reduction
Inventor: NADIM MOHAMMED
IPC: G10K11/178
Filed: 1992-04-09
Granted: 2002-01-22
Abstract: Primary vibrations (N), e.g. acoustic noise or vibration from a source thereof such as a motor, are cancelled by secondary vibrations (C) produced by an actuator (2) driven by a controller (3) that is responsive to an error signal (E) detected by a detector (4) and representative of the residual or difference between the primary and secondary vibrations. The controller samples the er-ror signal (E) during successive sampling periods determined by a synchronising signal (syn) taken from the motor. The secon-dary vibrations C n+1 for a sampling period n + 1 are determined as follows: C  n+1 = C n -µE n SGN(l/~], where C n represents the secondary vibrations produced during a preceding sampling period (n); E n represents the detected error signal for said preceding period n, H represents the transfer coefficient between the actuator (2) and the detector (4) and µ is a scaling fac-tor where 0 < µ < 1. The apparatus is in one embodiment configured as an add-on unit for a personal computer (PC) including circuit board which fits into an expansion slot of the PC.

Abstract: In a telecommunications system, automatic directory assistance uses a voice processing unit comprising a lexicon of lexemes and data representing a predetermined relationship between each lexeme and calling numbers in a locality served by the automated directory assistance apparatus. The voice processing unit issues messages to a caller making a directory assistance call to prompt the caller to utter a required one of said lexemes. The unit detects the calling number originating a directory assistance call and, responsive to the calling number and the relationship data computes a probability index representing the likelihood of a lexeme being the subject of the directory assistance call. The unit employs a speech recognizer to recognize, on the basis of the acoustics of the caller's utterance and the probability index, a lexeme corresponding to that uttered by the caller.

Title: Flotation coating device for travelling webs
Inventor: AIDUN CYRUS K
IPC: B05C3/18
Filed: 1994-05-16
Granted: 2005-05-10
Abstract: A coating applicator for application of coating material to the surface of a web or a flexible substrate.      The coating device contains a walled application chamber where a flowing stream of the coating liquid first comes into contact with the substrate. The coating liquid enters a channel of the application chamber at the upstream side and wets the substrate as it flows in the same direction as the substrate. A doctor element is positioned at the downstream side of the channel where the excess coating in the channel follows the contour of the boundary formed by the doctor element and leaves the channel. One of the applicator walls is designed to be a floating or moving wall or belt. The floating applicator wall and geometry of the streamlined boundaries of the coating device eliminates the formation of recirculating eddies or vortices. The elimination of vortices eliminates flow instability due to centrifugal forces and removes harmful pressure fluctuations which could result in coat-weight nonuniformities.

Title: Method of monitoring an area, and a device for carrying out the method
Inventor: GRUNER WILHELM
IPC: G01S13/34
Filed: 1993-12-01
Granted: 2002-03-26
Abstract: Monitoring an area with the aid of a frequency-modulated continuous-wave radar includes emitting a frequency-modulated continuous-wave transmitting signal with at least one transmitting antenna having a directional pattern whose main azimuthal direction depends on the frequency of the transmitting signal. Related to a predeterminable direction, an azimuthal region is selected, and in the selected region, an azimuthal swivelling of the directional pattern of the transmitting antenna is carried out by changing the frequency of the transmitting signal. Also in the selected region, each azimuthal value is assigned a frequency value of the transmitting signal.      The selected region is divided into a predeterminable number of azimuthal increments adjoining one another, and in each of the increments, a monotonous change of the frequency of the transmitting signal occurs. A reflected portion of the transmitting signal, which is reflected by the area to be monitored, is received with a receiving antenna, and a coherent signal processing for evaluating the receiving signal for each increment coherent signal processing is carried out.

Abstract: Drain Cleaning Apparatus for rotating a drain cleaning snake which is manually advanced through the apparatus comprises a frame and housing  assembly  supporting  an  axially displaceable non-rotating clutch actuating shaft which in turn supports a first annular clutch actuator for rotation relative thereto and axial displacement therewith.   A second annular clutch actuator  is coaxial with the first actuator and axially spaced therefrom and is supported in the housing for rotation relative thereto.  A radially expandable and contractible clutch is axially captured between the two clutch actuators and, in response to displacement of the first clutch  actuator  toward  the  second,  the  clutch  is  radially contracted to engage a drain cleaning snake extending through the clutch actuating shaft, the clutch actuators and the clutch.  A motor in the housing drives the first clutch actuator through a transmission pulley and belt arrangement including a pulley driven by the motor and with respect to which the belt is axially slidable in response to axial displacement of the first clutch actuator toward and away from the second clutch actuator.  The clutch and second clutch actuator are axially positioned in a shroud at one end of the housing,  and the position of the  second actuator relative to the first actuator is axially adjustable to adjust the initial contracted disposition of the clutch for the apparatus to accommodate drain cleaning snakes having different diameters.  The shroud is mounted on the frame for pivotal displacement axially outwardly from the remainder of the housing to facilitate removal and replacement of the clutch and access to the second clutch actuator and a housing portion adjacent the shroud is removable to provide access to the transmission components.

Abstract: The present invention exploits the herein first reported, empirical observation that even though staphylococci produce the enzyme, .beta.-glucosidase, this genus of bacteria is not able to produce a metabolite that will enzymatically react with 5-bromo-4-chloro-3-indolyl-.beta.-D-glucopyranoside, a substrate commonly used to detect the presence of .beta.-glucosidase produced by other bacteria. In view of this unexpected observation, one embodiment of the present invention includes a selective medium containing inhibitors to enhance staphylococci growth as well as a first glucopyranoside substrate. such as 5-bromo-4-chloro-3-indolyl-.beta.-D-glucopyranoside, and a second phosphatase substrate, such as 6-chloro-3-indolylphosphate or 5-bromo-6-chloro-3-indolylphosphate.  In this embodiment, staphylococci in a sample will produce metabolites that will react with the phosphate substrate in the medium to produce colonies having red to red-violet color while other bacteria in the sample will produce .beta.-glucosidase that will react with the glucopyranosidase substrate in the medium and produce colonies having a blue color.  In a particularly preferred embodiment of this invention, a thin film culture plate device, such as a PETRIFILM culture plate device, is prepared using a dry culture medium containing selected inhibitors, a first glucopyranoside substrate and a second phosphate substrate. When the thin film culture plate device is inoculated with a sample and then incubated for a sufficient period of time, staphylococci in the sample will produce colonies on the thin film device having a red color and other bacteria in the sample will produce colonies on the device having a blue color.

Abstract: A method is provided for thermo-chemical dewaxing of a large dimension line or conduit using a Nitrogen Generation System/Emulsion. The method involves introducing an emulsion into the conduit to be dewaxed. The emulsion comprises an internal aqueous phase and an external organic phase. The aqueous phase comprises an oxidizing nitrogen salt, a reducing nitrogen salt and water. The organic phase comprises a non-polar organic liquid, such as kerosene, and a delayed action activator for inducing the reaction of said oxidizing nitrogen salt and said reducing nitrogen salt. The delayed action activator may be a linear, aliphatic polyanhydride, such as poly(adipic anhydride). The emulsion is maintained in the conduit until the delayed action activator induces the reaction of the nitrogen salts to generate nitrogen and heat, thereby fluidizing wax in the conduit. The fluidized wax is then removed from the conduit. The emulsion may be prepared on a production platform or on nearby equipment. Well production may be resumed after the dewaxing treatment.
